Geological maps

Geological maps show the nature, extent and relative stratigraphical age of the different rocks within a district.The small scale maps (1:1 000 000; 1:625 000 etc), provide only summary information on the geology of the whole or part of the UK. More detailed information is shown on the 700 or more 1:50 000 scale maps which cover a district approximately 18 miles by 12 miles.

Larger scale maps at the 1:10 000 scale, covering a small area, are available for much of Britain. Maps at this scale normally provide the greatest level of detail available for most districts. These maps are produced on demand.
